【摘要】 分别对平板型、三曲线型、流线型翼型风量测量装置进行了实验研究。对三种装置给出了统一的理论流量计算公式；通过实验对其阻力特性和流量特性进行了研究。得出了平板型风量测量装置为最佳风量测量装置的结论更多还原

【Abstract】 Various types of air-flow measuring devices,inclding flat type,three-curved type,stream-line type and vane type,have been experimently studied and an unified theoretical formula to calculatie air-flow rate is established.Furthermore,by experimental study of their drag characteristic and flow characteristic,it is concluded that the flat type air-flow measuring device is the best one.更多还原
